Observation

Observation

An observation represents an "observed entity," that is, an entity that was observed by an observer. An observation often consists of measurements that refer to one or more measured characteristics of the observed entity. Observations may also be made within a broader context. The context of an observation is given by other observations, implying that an observed entity (and specifically each corresponding measurement) contextualizes another observed entity (and its corresponding measurements). For example, an observation of a location may serve as context for an observation of an organism. In this case, the observed characteristic values of the location (such as humidity) are assumed constant for the observation of the organism.
